Abstract. In this contribution we describe planktonic assemblages, comprising their taxonomic composition and palaeoecological attributes, from the La Colonia Formation, Patagonia, Argentina. The palynological samples are from the section exposed at Estancia San Miguel, in the Telsen area, Chubut province. Diverse organic-walled remains of Chlorophyta and Charophyta taxa are documented. These include coenobia of two species of Pseudopediastrum, colonies of Botryococcus and zygospores of the form-genus Ovoidites (resembling extant genera of Zygnemataceae). The green algae together with dinoflagellate cysts (analyzed in a previous detailed study) indicate brackish to freshwater and freshwater depositional conditions for the middle and upper part of the Estancia San Miguel section, respectively. These water bodies developed along a coastal plain in the northern Patagonia probably during the Paleocene, in a phase of the extensive first transgressive event of the South Atlantic. The earliest record of Pseudopediastrum brevicorne for Patagonia is presented.

Resumen. ANTIGUOS AMBIENTES COSTEROS EN UNA LÍNEA DE COSTA ATLÁNTICA DEL MAASTRICHTIANO– ?PALEOCENO: UN ENFOQUE DESDE EL FITOPLANCTON. En esta contribución se presentan asociaciones planctónicas, incluyendo sus aspectos taxonómicos y atributos paleoecológicos, de la Formación La Colonia, Patagonia, Argentina. Las muestras palinológicas estudiadas provienen de la sección expuesta en Estancia San Miguel, área de Telsen, provincia de Chubut. Se documentan diversos elementos de pared orgánica de taxones de Chlorophyta y Charophyta. Estos incluyen cenobios de dos especies de Pseudopediastrum, colonias de Botryococcus y cigósporas del morfogénero Ovoidites (similares a cigósporas de géneros actuales de Zygnemataceae). Las algas verdes junto a los quistes de dinoflagelados (presentados en un detallado estudio previo) indican condiciones depositacionales de agua salobre a dulce para la parte media y de agua dulce para la parte superior de la sección Estancia San Miguel. Estos cuerpos de agua se desarrollaron a lo largo de una planicie costera en el norte de Patagonia, posiblemente durante el Paleoceno, en una fase del extensivo primer evento transgresivo del Atlántico Sud. Se presenta el registro más temprano de Pseudopediastrum brevicorne para Patagonia.
